ClinConnect Summary
This clinical trial is looking at two different methods for taking dental impressions, which are important for orthodontic treatment. One method uses a traditional material called alginate, while the other uses a digital device called an intraoral scanner. The study aims to find out how long each method takes and how much they cost. Researchers will involve 68 orthodontic patients aged 9 and older who are visiting the Orthodontic Department at Queen's Medical Centre in Nottingham. Participants will be randomly assigned to either the alginate group or the intraoral scanning group, and the time taken for each impression will be recorded.
To be eligible for the study, patients must be at least 9 years old and need dental impressions for their orthodontic treatment. However, those with severe dental anxiety, certain medical conditions, or who refuse to participate will not be included. Participants can expect to have either the alginate impression or the intraoral scan done during their appointment, and the costs associated with both methods will be analyzed. This trial seeks to provide clearer information about the time and expenses involved in these two techniques, helping to improve patient care in orthodontics.
